Hi R2R. I've had a large infestation of red planaria for the last month or so. Since I have a fluval evo, I cannot add a melenarus wrasse, and I really don't want to have to use FWE to take care of what is mostly an eyesore. I've also heard about blue velvet nudibranch, but I can't find any for less than 30 each plus shipping. I was wondering what natural predator I could add to take care of my problem; I read about sixline wrasses, but a lot of people say they don't actively hunt for FW. I also read about spotted mandarins, pink streaked wrasses (a bit out of budget), and damsels. Please help!
